SAMUEL W. HOPE, OF DOVER, DELAWARE.

I IMPROVEMENT IN FRUIT-DRIERS.

Specification forming part of Letters Patent No. 172,740, dated January25, 1876; application filed October 16, 1875.

To all whom it may concern:

Be it known that I, SAMUEL W. HOPE, of Dover, in the county of Kent andState of Delaware, have invented a new and Improved Fruit-Drier, ofwhich the following is a specification The invention consists incombining certain means for removing moisture from fruit, as hereinafterdescribed, and pointed out in the claim.

Figure l is a sectional elevation of my improved drier. Fig. 2 is also asectional elevation, and Fig. 3 is a horizontal section.

Similar letters of reference indicate correspondin g parts.

A represents a flue-shaped drying case or chamber, to be made of anyapproved mate rial, and so constructed as to sit on afoundation-section, B, Which,by preference, will be of brick to theheight of the heater, or thereabout, the said dryingflue beingconstructed in such form and proportion that it will act as a flue fortaking up the air to the trays D, and by that means effect thecirculation. But, in

addition thereto, and for use in case of need,

I also propose to have a system of small tubes or fines, E, at one ormore sides, for taking some of the air up around or by the trays anddischarging it into the drying-flue again, between the trays, and alsoanother system, F, for drawing out the air from the spaces between thetrays as it becomes charged with moisture by evaporation of the moistureof the fruit, these latter fluesbeing open to the main flue or to theatmosphere at the top, for discharging, and the others, being providedwith valves J, to regulate the currents and direct them into thedifferent spaces, as required. In this example the flues of these twosystems are arranged alternately side by side; but, in practice, Ipropose to so arrange them that the same fines may be used to conductthe air from below into the spaces, or from the spaces to the place ofescape above, suitable valves or dampers being employed for convertingthem from the one condition to the other.

The attachment for utilizing the heat escaping from the smoke-pipe K,after it emerges from the Wall of the drying-flue, consists of the hoodL, built out around the lower portion of the pipe to catch the risingheated air, and the fiues'or passage M, to conduct the same into thedrying-flue.

The roof-plates Nare, in this example, made of metal, for the purpose ofcondensing the moisture of the air in the drier, so that it will escapeby flowing down through passage 0, or may be carried off by gutterssuitably arranged; but, in practice, I will construct the whole or anypart of the drying-flue of such material or glass, or anythat may befound most desirable. I

Having thus described my invention, I claim as new and desire to secureby Letters lPatent- The combination, with flueshaped chamber A, havingheater at bottom, of the trays D and the air-tubes E F, arranged tooperate substantially in the manner described.
